Living with LRP5-related primary osteoporosis

A rare inherited bone condition with low bone density and repeated fractures from small injuries, starting in childhood or the teen years.

Understanding LRP5-related primary osteoporosis

LRP5-related primary osteoporosis is a rare bone condition with reduced bone density and repeated fractures.

It causes compression fractures in the spine and repeated fractures in the arms and legs from low-impact injuries. This leads to bone pain and trouble moving. People typically have symptoms in childhood or adolescence.

Signs & symptoms

GARD doesn't list a separate symptom list. Its summary describes these features:

  • Low bone density
  • Spine compression fractures
  • Repeated fractures from low-impact injuries
  • Bone pain
  • Trouble moving (impaired mobility)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists and genetic specialists.

  3. Consider genetic testing

    Changes in LRP5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
